I checked the similiar threads, but didn't see anything that directly addressed this. I had trouble getting my Moment to be seen by my laptop. I followed another thread that said to turn off the USB debugging. After that, the driver is installed without issue. But, when I go to my computer window (Windows 7), I see the phone is assigned drive letter E, but it's grayed out. Do I need to do something else to get it to be "active"?
